The Ellsworth Mountains are a prominent mountain range located in Antarctica, specifically in the region known as the West Antarctic. They stretch approximately 1,200 kilometers (750 miles) and are home to some of the highest peaks on the continent, including Mount Vinson, which stands at 4,892 meters (16,050 feet) above sea level. The range was first discovered in 1935 by the American explorer Lincoln Ellsworth, after whom it is named. This mountain range is characterized by its rugged terrain and extensive glaciers, making it a significant area for scientific research, particularly in the fields of geology and climate studies. The Ellsworth Mountains are part of the larger Antarctic Peninsula region, which is experiencing notable changes due to climate change. The area is largely uninhabited, with only a few research stations operated by various countries.
